How this calculator works
- The as-of date is the date you want to calculate the employee's FMLA balance.
- The calculator counts FMLA leave used during the 12 months before the as-of date.
- Leave entries older than the 12-month lookback period do not count toward the current used total.
- Leave entries after the as-of date do not count in this v1 calculation.
- The result is an estimate based only on the entries provided.
